Abstract
PCT No. PCT/EP95/04873 Sec. 371 Date Jun. 16, 1997 Sec. 102(e) Date Jun. 16, 1997 PCT Filed Dec. 11, 1995 PCT Pub. No. WO96/18761 PCT Pub. Date Jun. 20, 1996A process for manufacturing formed objects such as fibers, filaments, yarns, films, membranes in form of flat membranes, hose membranes and hollow fiber membranes and the like, involves pressing cellulose solutions in an amine oxide of a tertiary amine and if necessary water, in particular in N-methylmorpholine-N-oxide and water, through a nozzle and precipitating the solutions in a coagulation bath and washing the formed objects obtained. The coagulation bath liquid and the washing water is processed, if necessary, for recovery of the amine oxide of the tertiary amine. Hydrogen peroxide, peroxyethanoic acid, ozone or chlorine dioxide is added to the coagulation bath and/or the washing water. The substances added can preferably be decomposed catalytically or by enzymes prior to the recovery process of the water and the solvent.
